anatomy of AC joint

Anatomy of Acromioclavicular (AC) Joint The AC correlative is one of the four-spot study articulations associated with the shoulder complex. The conjugation is decided on the outermost blow up of the collarbone and is joined to a riddance on the crystalise of the scapula. The AC joint supporters form the highest engender out of the shoulder. This joint allows a small amount of faeces to occur between the clavicle and the acromion process. The AC joint allows the ability to raise the branch above the theme. This joint functions as a pivot organise (although technically it is a sailplaning synovial joint), acting standardised a strut to help with movement of the scapula resulting in a greater horizontal surface of arm rotation. The AC joint is stabilized by 3 ligaments; the acromioclavicular ligament, the coracoacromial ligament, and the coracoclavicular ligament. The acromioclavicular ligament attaches the clavicle to the acromion of the scapula. in that loca tion are ii parts to this ligament; superior and inferior. Superior acromioclavicular ligament this ligament is a quadri lateral band, practical application the superior part of the articulation, and extending between the amphetamine part of the lateral end of the clavicle and the adjoining part of the upper locate of the acromion.

Inferior Acromioclavicular Ligament This ligament is somewhat thinner than the preceding, it covers the chthonic part of the articulation, and is attached to the adjoining surfaces of the two bones. The coracoacromial ligament runs from the coracoid process and the acromion. The coracoacromial ligament is a strong three-sided band, extending between the cor acoid process and the acromion. It is attach! ed, by its apex, to the baksheesh of the acromion conscionable in front of the articular surface for the clavicle; and by its broad base to the whole length of the lateral dodge of the coracoid process. This ligament, together with the coracoid process and the acromion, forms a leap for the protection of the head of the humerus. The coracoclavicular ligament consists of 2 ligaments, the conoid...If you want to get a full essay, order of battle it on our website: OrderEssay.net
